陈老师:
18. It’s the third time _____ late this month.
A. that you arrived B. when you arrived C. that you’ve arrived D.when you’ve arrived。
老师,这道题选D为什么不可以?
解答如下:
答案解析C 为正确答案.关于以上句型要注意以下2点。
(1)句式结构:“This/It is/was the first/second ... last time + that从句”表示“这是第……次做某事”。其中,that引导的是定语从句,that在口语中常省略。
(2)句式时态:我们需要掌握that从句的时态:若前面的be动词为is,从句通常用现在完成时;若其为was,则从句用过去完成时。
(1) It is the +序数词+time that+ 主语 +have/has done sth
It is the first time that I have written to a foreign pen friend.
这是我第一次给外国笔友写信。
(2)It was the +序数词+time that+ 主语 +had done sth
It was the third time that he had asked the same question.
这是他第三次问同一个问题。
(与上面句子结构相类似句型拓展如下)
句型“It is (high) time + that从句”的意思是“该做某事了”,其中that从句的谓语动词常用虚拟语气,即“should + 动词原形”或用动词的过去式。
It is ten o’clock. It is high time that we went to bed.
= It is ten o’clock. It is high time that we should go to bed.
10点钟了,该是我们上床睡觉的时候了。
继续跟踪解答如下
老师,that在句子中充当什么成分?
that在这里充当关系副词语法功能,在定语从句作状语成分,因为定语从句很完整,主语和宾语都不缺,在口语中that经常省略,另外that在这个句子结构中属于that特殊用法. that在定语从句充当主语,宾语等用法有所不同,要加以区别和注意。
(备注:that在以上充当关系副词语法功能,相当于for which =for the third time。结构,其中which=the third time.)
It was (high) time that+主语+ should+v.老师,这个虚拟句型里的that用when替换吗?
继续跟踪回答:
不可以更换为”when",在这个句型和上面句型中,引导定语从句必须使用“具有关系副词语法功能that”引导,不可以使用when.
(这里具有关系副词语法功能that 相当于in which;which=the time,可以按照这样来理解,但是不能那样写出来。因此这属于that当作关系副词使用特殊用法。)
(特别注意:如果从句使用be形式,则只能用were,如果使用 should+动词原形, 则should不可以省略。)
